Took 10 yo DS to GP yesterday. For months he's had greasy, yellow diarrhoea with undigested food in it. No stomach ache or bloating but he is skinny and complains of being tired.
The GP has ordered bloods but has also recommend DS goes gluten free for a month to see if it makes any difference but I'm wondering if that is correct advice? Everything I've read says you must stay on gluten in order to get a clear result.
Can anyone advise on the right course of action?
